How To Generate Multiple DropDownLists

Aug 5, 2010

I have to generate multiple dropdownlists on clientclick. That is new dropdownlists on every client click.
I placed a button and wrote code on click event. protected void addReq1_Click(object sender, ImageClickEventArgs e)

{
DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
tc2.Controls.Add(oDdl);
HtmlTableRow tr = new HtmlTableRow();
tr.Cells.Add(tc0);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
tr.Cells.Add(tc3);
search2.Rows.Add(tr);
}

Here "DSUsers" is SqlDataSource. "i" is static variable. "serarch2" is html table with runat server tag The problem is only one control is getting rendred, after that on every additional click same DropDownList is getting replaced. No new DropDownList is added to the page.

Web Forms :: How To Generate HTML Code By Commands From The Code Behind Page

Dec 30, 2010

how to generate HTML code from the code behind?

I would like to build a form that generate an html code inside a for loop.

I will let the user enter the photo name and No. of photos

Then I will generate an HTML code like this:

<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />

depending on the No. of the photos the code will be duplicated in the loop

Then I will display the result of the loop in label or in a textarea to let the user copy it any where

The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses

Web Forms :: Want To Dynamically Generate Asp Controls From Code Behind

Mar 29, 2010

On my form I want to display n number of rows of asp textboxes where n is determined by the number of records in the corresponding database table. I can dynamically generate html controls and get the values via request.form but I can't figure out how to do the same with asp controls.

The output from the following code, displays the text boxes from the "input type=text" statement, but displays nothing for the "asp:textbox" statement. I would prefer to use asp (or third party controls) so would greatly appreciate help on how to render non-html controls dynamically from my code behind.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
Dim ncount As Integer = 0
Dim strOutput As String = "" [code]....

Web Forms :: OnClientClick - How To Generate Neat HTML / JavaScript Code

Jan 28, 2011

I have a page with a control like this:

<asp:Button ID="test" runat="server" Text="test" OnClientClick="pageTracker._trackPageview('/bezichtigingsform/deeplink')" />
The OnClientClick-attribute is rendered as:
onclick="pageTracker._trackPageview('/bezichtigingsform/deeplink')"

When I try to escape the single-quote like this "'" or with a double backslash preceeding the single quote, this does not work. I also tried it like this:

string str = "pageTracker._trackPageview('/bezichtigingsform/deeplink'";
test.Attributes.Add("onclick", str.Replace("'", "\'"));

and of-course I tried all possible escaping-combinations in the above too.

It seems like asp.net just encodes the value, but how can I stop this? I want to be able to generate neat html/javascript-code...

DropDownLists Affecting Other DropDownLists?

Jun 25, 2010

I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.

Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.

MVC - Generate An ActionLink From Code Behind?

Jan 4, 2010

I have a number of permissions, and based on a set of conditions these permission determine if a user can see certain features. I have written a helper function for this as the logic in the view became quite extensive.

Essentially I'm looking for a function the same as Html.ActionLink that I can access from a class file (Ideally if I can access the Helper that would be great) So I can do somthing like so,

public static string GetAdminLinks()
{
if(PermCheck)
{
return(Html.ActionLink(...));
}
}

How To Generate Code-behind File For Each View In The Project

Jan 11, 2011

In ASP.NET MVC Application I would like to document my Views, so that I can generate a documentation (using NDoc). Since Views do not have a code behind the documentation should go somewhere into the View directly. I also do not want to generate code-behind file for each View in the project

Is there a tool/workflow/configuration that would allow me to extract inline documentation comments from aspx files (Views)

Add Web Reference Does Not Generate Asynchronous Proxy Code?

Jan 28, 2010

I am trying to add a web reference to an ASP.NET 2.0 application in Visual Studio 2008.However, the generated proxy classes do not include BeginXXXX and EndXXXX methods.Hcan I get these to be generated? Do I need to manually use wsdl.exe?(Incidentally in ASP.NET 3.5 apps, there is an option in the Add Service Reference box which lets me specify that Async methods should be generated. However, I am limited to ASP.NET 2.0 implementation).

ADO.NET :: Can't Get Dataclasses1datacontext To Generate Code Behind In .net 4.0 And Vwd 2010 Express?

Sep 20, 2010

I am using a web application project in visual web developer express 2010 on Windows 7 x64 targeting .net 4.0. I've linq to sql quite a bit with visual studio 2008 and it worked with no issues. I added a dbml file to the root of my web site and dragged over my data model. When I run my project, I get the following error:

Type 'DataClasses1DataContext' is not defined. The line of code it is having a problem on is Dim db As DataClasses1DataContext = New DataClasses1DataContext()

However, intellisense is recognizing dataclasses1datacontext as a valid class. If I view the code on the dbml file, it has essentially an empty class definition. It appears it didn't actually generate any code relating to my data model. I tried adding system.data.linq, etc to my web.config file but it didn't make a difference. I always get the error above. Again, I'm using a web application project which appears to function a little differnetly than a web site project. Any ideas why I can't get this basic functionality that was working in 2008 to work in 2010?
